I have an E4200IR modulator, I noticed the numbers start showing as 0.1, 0.2, etc. What does this mean?

Asked By – On June 30, 2014 – With Comments Off

On the E4200IR, once you are in the cable channel range (65-135) and you are over 100, each subsequent number will display as 0.0 (100), 0.1 (101), 0.2 (102) and so on. This is because there are only 2 fields to list channel number.

I purchased a P-0328 Affinity Digital Cable Combiner, however it only came with one remote and one IR receiver. Is it possible to purchase extra remotes and IR receivers separately?

Asked By – On June 30, 2014 – With Comments Off

Yes you can purchase the extra 7 A0511 remotes which will allow you to switch back and forth between modulation, and cable. You can also purchase the extra IR-4101 receivers which will allow the signal from the remote to route to the P-0328 and switch between cable/modulation. You would need 7 of each to utilize ...

The problem is it seems I can only control the device from one location at a time. If I “reset” the IR4000 by pulling the power and putting it back in, sometimes it switches to the other location. Sometimes this just happens randomly. Have I set something up incorrectly?

Based on the information that you provided, there are a few variables which can impact the viability of the IR over coax system. First, make sure that you have terminated the unused ports on the HS-4 with 2101 F Male Terminators. The IR passes on the coax through the DC voltage, therefore if at any ...

Could you please suggest equipment that would allow for us to modulate 18 composite video sources (12 SD cameras and 4 CATV cable boxes) with distribution to 14 flat panel displays. Note that we will not be using the tuners in the cable boxes….just the flat panels.

  The largest modulator manufactured by Channel Vision is the E4200IR which is a 4 channel modulator. To get 18 modulated channels you would need to purchase either five E4200IR’s, or four E4200IR’s and two E1200′s (single channel modulators). You would then assign different channels to each of the sources, leaving a channel in between each to ...

We currently have a 4 input / channel RCA / composite video Modulator sent to a CVT-38BID and then split to the TV network. I would like to send HDMI to that same network. can I send modulated HDMI through the CVT-38BID?

Asked By – On April 18, 2014 – With Comments Off

If you are modulating within the frequency supported by the CVT-38-BID, then yes you can send the signal through the amplifier. The CVT-38BID supports a frequency range between 54-1000 MHz. You will need to look at your modulator to confirm you are using a channel frequency that falls under this range.

I just switched to digital cable and I can no longer view my modulated feed? Do I need to buy a new modulator that is compatible with digital cable?

Asked By – On March 28, 2014 – With Comments Off

Using a Channel Vision modulator, you can not combine with digital cable. Because of recent changes in the digital frequency by cable companies it is no longer possible to use a standard RF modulator to combine with cable TV. We offer a unit called the Affinity Digital Cable Combiner (P-0321, P-0328) which functions as a ...

Why do I need to use terminators on amplified splitters?

Asked By – On March 28, 2014 – With Comments Off

If you do not use terminators on the amplified splitters you may experience RF signal loss, by capping the unused terminals with a 75 ohm terminator you prevent the signal loss and allow for a stronger signal to reach your proposed RF drop.

Does Channel Vision manufacture any splitters for Satellite cable distribution?

Asked By – On March 28, 2014 – With Comments Off

No, Channel Vision does not manufacture any splitters that are able to to pass the frequency that Satellite Cable uses.
